Hochspannungsverstärker

The fast response high voltage amplifier HVA-3B4 is a 19” rack-mountable unit of 3U. Four channels provide output voltages in the range of –3000 V to +3000 V at load current of ±1 mA each. The four channels can be used independently or two channels at a time can be switched to differential output mode.

The precision high voltage amplifier HAR12A is a 19" rack-mountable unit of 3U. Twelve channels provide output voltages in the range of -500V to +500V at load current of ±2mA each. Both the output voltage and the load current of each channel can be displayed simultaneously on two 4-digit red LED-displays. A rotary switch for channel selecting is provided. High-Speed versions up to 15kHz bandwidth / 50V/µs slew rate are available on request.

The HAR2 is a mainframe to be equipped with one or two high precision high voltage amplifier modules HA05B2. The output voltage is controlled by a control voltage or set by a 10-turn potentiometer. The control voltage ranges from –10V to +10V, the gain is 50.Both the output voltage and the load current of a selected channel can be displayed simultaneously on two 4-digit LED displays. All amplifier outputs are protected against overload, short circuit and transient overvoltage.High-Speed versions up to 15kHz bandwidth / 50V/µs slew rate are available on request. The HAR2 is available as a tabletop or a wall mountable model (HAR2-W).

The precision high voltage amplifier HA05B2 is a standard 19" plug-in unit of 3U / 6HP. It features very high stability and low noise, thereby making the unit well suited even for voltage reference applications. The output voltage is controlled by a control voltage which can be either provided via its nominal value input or set by a 10-turn potentiometer. Monitor outputs for voltage and current are provided.
